Preliminary data, comprised of over 3,000 images, will enhance predictions for future robotic and crewed landings, aiding in the development of surface infrastructure in proximity to landing zones.
- The ongoing SCALPSS project aims to create 3D digital elevation maps of the Moon’s surface and plans to publicly release raw images within six months, with a new version of the instrument set to support future missions, including one on Blue Origin’s Blue Moon lander.
NASA has made history by capturing groundbreaking footage of a lunar lander’s engine plumes interacting with the Moon’s surface. A team at NASA’s Langley Research Center in Hampton, Virginia, achieved this milestone using the Stereo Cameras for Lunar-Plume Surface Studies (SCALPSS) 1.1 instrument. The remarkable imagery came during the descent and successful landing of Firefly Aerospace’s Blue Ghost lander on March 2. This event took place in the Mare Crisium region as part of NASA’s Commercial Lunar Payload Services initiative.
The video, though compressed and limited in resolution, showcases a sequence that researchers compiled from the instrument’s four short-focal-length cameras. These cameras captured photos at 8 frames per second starting about 91 feet above the lunar surface. Interestingly, they documented how Blue Ghost’s thruster plumes began affecting the lunar landscape at approximately 49 feet. As the lander descended, these plumes stirred up the Moon’s dust and rocks, known collectively as regolith. After landing, the thrusters shut down, allowing the dust to settle, revealing the terrain below.
Rob Maddock, the SCALPSS project manager, noted the significance of this data. “The 3000-plus images we captured contain vital information for understanding plume-surface interactions. This knowledge will help reduce risks for future lunar landers and surface infrastructure,” he emphasized. As lunar missions increase, scientists require accurate models to predict the effects of landings. Data from SCALPSS will help refine these models for both robotic and crewed missions.
The SCALPSS 1.1 technology includes not only short focal length cameras but also two long-focal-length cameras. This combination allows researchers to assess changes in the lunar surface before and after landing, creating detailed 3D elevation maps. As the lunar day progresses, sunlight will reveal even more details around the Blue Ghost lander, enriching the data collection experience.
Michelle Munk, the principal investigator of SCALPSS, highlighted the importance of this project. “Gathering knowledge about landing and operation on the Moon is essential. The data from this technology will benefit future missions,” she stated. Over the coming months, researchers will process the extensive data collected. They anticipate releasing raw images to the public through NASA’s Planetary Data System within six months.
Looking ahead, the team is preparing for their next mission, involving Blue Origin’s Blue Moon lander, set to launch later this year. The next version of SCALPSS is currently undergoing thermal vacuum tests at NASA Langley. This initiative demonstrates how collaboration with American companies under the CLPS initiative continues to push the boundaries of science and technology on the lunar surface. As exploration expands, each successful mission brings humanity closer to understanding and utilizing the Moon’s potential.
